The answer is latent evidence. Evidence that can't be seen by the naked eye. These are hidden pieces of evidence.This evidence needs special tools, chemicals or materials to exposed them. Such items like cyanoacrylate fumes and UV light source are used to see the finger print on a gun.
Answer : The final volume at STP is, 1000 L
Explanation :
According to the Boyle's, law, the pressure of the gas is inversely proportional to the volume of gas at constant temperature and moles of gas.

or,

where,
= initial pressure = 1520 mmHg = 2 atm (1 atm = 760 mmHg)
= final pressure at STP = 1 atm
= initial volume = 500.0 L
= final volume at STP = ?
Now put all the given values in the above formula, we get:


Therefore, the final volume at STP is, 1000 L
